Sets the steps for the currently authenticated player towards unlocking an achievement. If the steps parameter is less than the current number of steps that the player already gained for the achievement, the achievement is not modified.

Get high scores, and optionally ranks, in leaderboards for the currently authenticated player. For a specific time span, leaderboardId can be set to ALL to retrieve data for all leaderboards in a given time span. NOTE: You cannot ask for 'ALL' leaderboards and 'ALL' timeSpans in the same request; only one parameter may be set to 'ALL'.

Create a rematch of a match that was previously completed, with the same participants. This can be called by only one player on a match still in their list; the player must have called Finish first. Returns the newly created match; it will be the caller's turn.

Returns turn-based matches the player is or was involved in that changed since the last sync call, with the least recent changes coming first. Matches that should be removed from the local cache will have a status of MATCH_DELETED.
